The present invention relates to new and useful improvements in steelroof or span constructions and has for its primary object to provide, ina manner as hereinafter set forth, a structure of this character ofnovel form whereby a comparatively large area may be covered without thenecessity of using intermediate supports, such as posts, pillars, etc.

Another very important object'of the invention is to provide a roof orspan construction of the aforementioned character which may beexpeditiously erected and taken down without the necessity of usingspecial tools or machinery,

Still another important object of the invention is to provide a roof orspan structure of the character described which may be of any desireddimensions. v

Other objects of the invention are to provide a roof or spanconstruction which will be comparatively simple, strong, durable, lightin weight and which may be manufactured and erectedat..

low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in side elevation of an embodiment of the invention.g c

Figure 2 is an elevational view ofanend portion of therooi'.

Figure 3 is a view in vertical sectionv through of the plates. 7

Figure 5 is a cross sectional view through a portion of the roof.

Figure 6 is a detail view in perspective of one of the arch brackets.

Figure 7 is a detail view in perspective of one of the arch segments.

will also be noted that the struts I! are of sufli- Figure 8 is a detailview insperspectlve of one of the arch braces.

Figure 9 is a detail view in elevation of one of the rings for thecrossed arch braces.

Figure 10 is a view in side elevation of a portion of another form of heinvention.

Referring now to the rawings in detail, it will be seen thatthereference numeral l designates including turnbuckles I fortightening.

Rigidly secured at spaced points on the plates 2 are brackets 6. Thereference numeral 1 designates generally a plurality of spaced arches ofsuitable metal which'are mounted on the brackets 6. Each arch 1comprises a plurality of segments 8 having overlapping end portionsrigidly secured together through the medium of bolts 9.

Extending between thearches l are pairs of. crossed braces III. Thebraces II are provided with eyes II on their ends which'accommodate thebolts 9. Thus, the same bolts which secure the segments I together alsosecure the braces II to the arches. Rings ll connect the crossedcollapsing. The ends of the struts I! are secured to the joints of thearch segments 8. It

cientlength to skip several of the segments I of the archesiL Thereference numeral l3 designates roofing mounted on the arches 1. Ofcourse, the roofing it conforms to the curvature of the arches I and,referring to Figure 5 of the drawings, it will be seen that the sectionsof said roofing are of 'sumcient width to extend between the adja-- centarches. The roofing sections l3 comprise. overlapping marginal portions2| which rest on the arches I. The portions 2| are provided withinterlocked V portions II which extend adjacent the opposite sides ofthe arches I. Then, the

roofing is firmly securedto the arches through tliemeciium of J boltsl5. Washers IQ of suitable material "are provided beneath the bolt nutsI! for preventing leiikage around the bolts;

It will thus be seen that a metallic roof or span has been provided ofsuch construction as ,to obviate intermediate supporting pillars, etc.

It will also be observed that-the structure may be expeditiously erectedwithout the use of special equipment. Further, the structure may betakendown if desired and there 'will- .be practically no-- loss of material.

/ inner and outer arches i8 and I9, respectively, 0

a pair of spaced walls. Mounted on the walls I are metallic plates 2which are secured by anchors 3, Extending between the plates 2 on thewalls I In Figure 10 of the drawings'there is illustrated a modificationto be used when unusual strength is desired. This modification compriseswhich are spaced from each. other through the medium of braces 20." Inother respects, this; modification issubstantially similar inconstruction to that form of the invention shown in Figs. 1 to 9,inclusive.

It is believed that the many advantages of a steel roof or spanconstruction in accordance with the present invention will be readilyunderstood and although preferred embodiments are as illustrated anddescribed, it is to be underat their ends, in eyes engaged with thejoints of the arch segments, securing elements passing 'through the eyesand the overlapping end portions of the segments for rigidly securingsaid segments and crossed braces together, and rings connecting thecrossed braces at the points where they intersect.

A structure of the class described comprising a plurality of spacedarches, roofing mounted on said'arches, said roofing comprising sectionsincluding overlapping marginal portions resting on the arches, saidoverlapping portions including substantially V-shaped interlockedportions on opposite sides of the arches, and means for anchoring theroofing sections on said arches.
